RAILJOINT CHAIR.

Specification of Letters Patent.

Aljanteirted Auen 18, 1.91/1.

Application iled January 7, 19111. Serial No. 810,803.

To all ell/0m it may concern;

Be it known that l, vlllf'rcnmiu J. McKen- Zi'n, a citizen of theDominion of Canada, residing at Nederland, in the county of jonlder andState of Colorado, have invented certain new and useful Improvements inRail-Joint Chairs, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention comprehends certain new and useful improvements in railjoint chairs and has for its primary object to provide a rail jointchair which will be of extremely simple construction and operation andwhich will include a wedge member which serves to draw together', theparts of the rail joint chair and cause the same to clamp the rail endssecured in said chair.

Another object is to provide a device of this character which will beconstructed in such manner that as the parts are forced together, thewedge member will draw downwardly upon the sections of the rail jointchair and at the same time, force the rail ends upwardly7 therebysecurely clamping the rail ends in position and preventing movement ofthe same as the wheels of the rolling stock pass over the oint.

A further object is to generally improve and simplify the constructionand operation of devices-of this character and increase the efliciencyof the same, without increasing the cost of manufacture thereof.

With the above and other objects in view, my invention consists incertain novel constructions, combinations, and arrangements of parts tobe hereinafter more fully described, claimed, and illustrated in theaccompanying drawings, in which,

Figure 1 is a transverse sectional view through my device in use; andFig. 2 is a lragmentary side elevational view of one of the rail jointchair members, looking at the inner face thereof.

Referring more specifically to the drawings in which similar referencecharacters designate corresponding parts throughout the several views, 1and 2 designate the rail joint chair members which include theupstanding portions 3 for engagement against the web portions of therail ends l and the lower portions 5 for engagement upon opposite sidesof the base portions of said rail ends.

The base portion G of the rail joint chair member 1 is of such width asto extend beneath the entire base portions of the rail` ends d and hasits upper face inclined transversely, the purpose of which willpresently appear, The rail joint chair member 1 also has its under facecut away along its free or inner longitudinal edge to form a channel 7to receive the narrow base portion 8 of the rail joint chair member 2.

It will be understood that the upstanding or web engaging portions ofthe rail joint chair members 1 and 2 are provided with the usual boltopenings 9 to receive the bolts 10 for drawing together said rail ointchair members and causing the same to clamp and hold together, the railends 41.

In order to draw the rail joint chair members 1 and 2 tightly againstopposite sides of the web portion of the rail ends 4- as the nuts 11 aretightened upon the bolts 10, l have provided a wedge member 12positioned beneath the base portions of the rail. ends 4l and restingupon the inclined upper face of the base portion 6 of the rail jointchair member 1, which wedge member 12 will also serve to force the railends 4L upwardly as the wedge member 12 is forced to proper position bythe drawing together of the rail joint chair members 1 and 2, said wedgemember 12 riding upwardly upon the inclined upper face of the baseportion 6.

The rail joint chair members 1 and 2 have the outwardly directedperforated flanges 13 to receive the usual railway spikes 14;. The railjoint chair members 1 and 2 are also provided with the downwardlydirected perforated flanges 15 between the outwardly directed perforatedflanges 13 and. adapted for engagement between the ties 16. Thedownwardly directed perforated. flanges 15 are adapted to receive thebolts 17 extended transversely beneath the rail ends l. and the railjoint chair members 1 and 2 and are adapted to draw toward one anotherthe "ail joint chair members 1 and 2 and retain the same in properrelation to one another and to the rail ends 4.

From the foregoing, it will be seen that I have provided a rail jointchair which will be of extremely simple construction and operation andwhich will securely clamp the rail ends in position and prevent movementof the same by wheels of the rolling stock passing over the joint.Further, it will be clearly apparent that, owing to the wedge member,and the construction of the rail joint chair members, they will not beloosened and thereby allow play of the rail ends by the strain to Whichthey are subjected by rolling stock passing over the joint, as is thecase with the forms of rail joint chairs now in general use. j

lhile have shown the preferred embodiment of my invention, it Will beunderstood that minor changes in the details oi construction andarrangement of parts may be made Within the scope of the appended claimsWithout departing from the spirit oit my .invention or sacrificing anyoi the advantages of the same.

What l .claim is l. A device oi' the class described comprising a railjoint chair member having an upstanding portion and a base portionprovided With an inclined upper face, a 'Wedge member positioned uponsaid inclined upper face, a second' rail joint chair member having anupstanding portion and a base portion, the upstanding portions of therail joint chair members being adapted for engagement with the oppositefaces oi the web portions of meeting rail ends, the upstanding portionof the second member being also adapted to bear against one edge of saidWedge member, and means for sebase portion being provided with a channelN along its inner lovver longitudinal edge, a second rail joint chairmember having an opstanding portion and a base portion, said f baseportion being adapted tor engagement in said channel in the base portionof the l `first member, the upstanding portions of f the rail jointchair members being adapted i'or engagement with opposite faces of. thej web portions of meeting rail ends, a Wedge l member positioned uponthe inclined upper lface oi. the base kportion of the first memtbei, andmeans for securing the upstanding portions oiE the rail joint chairmembers against the meeting rail ends. in testimony whereof I hereuntoaiiix my signature in the presence of tWo Witnesses.
